SHZF3 SCR Power Controls (Three Phase, 30-225A Amps)

SHZF2 series SCR power controls arethree leg, three phase zero-fired power controls designed to deliver maximum power control and reliability for the most demanding applications.Zero fired, three phase,threeleg control can be used in most three phase resistive/heater load applications.Zero fired units turn on and off full sine waves rapidly for precise power control. The controls use variable time base for very high output resolution.
